在做WinForm時(shí)，想做一個(gè)像Asp.Net里的ImageButton的控件，于是自己寫(xiě)了一個(gè)自定義控件，名為：ImageButton，繼承PictureBox類(lèi)，并實(shí)現(xiàn)IButtonControl接口，但是實(shí)現(xiàn)IButtonControl接口時(shí)必須重寫(xiě)IButtonControl的NotifyDefault(bool value) 和 PerformClick()方法，還有 DialogResult { get; set; }屬性，我的代碼如下，可是里面的PerformClick()方法我不會(huì)寫(xiě)，請(qǐng)高手指導(dǎo)一下。

using?System;
using?System.Collections.Generic;
using?System.ComponentModel;
using?System.Drawing;
using?System.Data;
using?System.Text;
using?System.Windows.Forms;

namespace?MyControls
{
????public?partial?class?ImageButton?:?PictureBox,IButtonControl
????{
????????private?DialogResult?dialogResult;

????????public?ImageButton()
????????{
????????????InitializeComponent();
????????}

????????public?void?PerformClick()
????????{
????????????//這里面的代碼不會(huì)寫(xiě)
????????}

????????protected?override?void?OnPaint(PaintEventArgs?pe)
????????{
????????????//?TODO:?在此處添加自定義繪制代碼

????????????//?調(diào)用基類(lèi)?OnPaint
????????????base.OnPaint(pe);
????????}

????????public?virtual?void?NotifyDefault(bool?value)
????????{
????????}

????????public?virtual?DialogResult?DialogResult
????????{
????????????get
????????????{
????????????????return?this.dialogResult;
????????????}
????????????set
????????????{
????????????????this.dialogResult?=?value;
????????????}
????????}

????}
}
